Asynchronous parser of OLH

The Danish project realizes a parser for the website of advertisements.
When performing the program the user needs to enter the name of the category of announcement, яку він бажає спарсити. The script verifies the availability of a JSON file with all available categories of advertisements and reflects this file. After this, the parsing of the vibrant category begins, the results are stored at the corresponding JSON file and this file is opened to be viewed.
The entire parsing process occurs asynchronously, which allows optimization of the program performance time.
